Could a Facebook Profile throw a wrench in your future??

In this story, by Rebecca Dince,  she gets alot of feedback on whether or not employers should look at Facebook Profiles before hiring their employees.  The way I see it is, Facebook is a public site.  Yes, you can make your profile public.  Anyone can use this site, young, old, even if they have a criminal back ground.  I think that what you do in college is your own doing.  If you want to go out and enjoy a night of partying, why put it up on social media?? There is no point in doing this.  I think that employers have every right to look at Facebook before someone gets hired at any job because they should know what kind of person their hiring.
